Indestructible Solar Light

Introduction: Indestructible Solar Light

Being alone, in the dark, on a cold, damp night isn't an experience that most people want to have. Unfortunately, it happens.

Sometimes it happens because your flashlight ran out of battery, got dropped and broken, or you just forgot to bring a flashlight. This light was made to help you with all of these problems. Except the last one. It can't help you with that. Sorry. :-)

Step 3: Assembling

If your solar unit is not tight inside of the PVC cap, you need to wrap it with electrical tape until it fits snugly. Don't press the unit into the cap yet, though. First, you need to take the cap, and drill a 3/8" hole directly in the center of it. This hole is to let the light through. Now you can insert your unit into the cap. The fit should be very snug. If you can get it back out, then you didn't do it right. :-)

Step 5: Conclusion

I know nothing is really "Indestructible," but this is pretty close. There are several things you could do to it that may improve practicality, but decrease " indestructibility." One of these ideas is to add a switch to control the light. Currently, the light comes on when it doesn't sense other lights. There are two reasons I didn't add a switch: First, I wanted to keep the project simple. Second, I didn't know how to waterproof it.

Congratulations! You now have a working, "indestructible", solar survival light that can shine for over 10 minutes on a 30 minute charge! This design has been drop-tested from 20+ feet and soaked in water for over 30 minutes, and it still works! Enjoy your newly constructed solar light, and thank you for reading this Instructable!
